With integrated graphics you don’t need to buy a separate graphics card.

3.Uses big.LITTLE technology

Huawei P8

Lava Iris 502

Samsung Galaxy Note 8 (Qualcomm Snapdragon 835)

Using big.LITTLE technology, a chip can switch between two sets of processor cores in order to maximise performance and battery life. For example, when playing a game the more powerful cores will be used to increase performance, whereas checking email will use the less powerful cores to maximise battery life.

4.Has out-of-order execution

Huawei P8

Lava Iris 502

Samsung Galaxy Note 8 (Qualcomm Snapdragon 835)

Optical image stabilization uses gyroscopic sensors to detect the vibrations of the camera. The lens adjusts the optical path accordingly, ensuring that any type of motion blur is corrected before the sensor captures the image.

3.Has laser autofocus

Huawei P8

Lava Iris 502

Samsung Galaxy Note 8 (Qualcomm Snapdragon 835)

A laser autofocus system quickly determines the depth of the subject you want to focus on, allowing you to take photos much faster.

For example

Huawei Honor Magic 2

4.Has a dual-lens (or multi-lens) main camera

Huawei P8

Lava Iris 502

Samsung Galaxy Note 8 (Qualcomm Snapdragon 835)

A dual-lens camera captures two images and overlays them. This technology creates sharper images, especially in low light conditions, and allows you to use effects such as softening the background.

5.Has phase detection autofocus for photos

Huawei P8

Lava Iris 502

Samsung Galaxy Note 8 (Qualcomm Snapdragon 835)

A phase detection autofocus is much faster than a contrast detection autofocus, allowing for sharper images.

6.has a brand lens

Huawei P8

Lava Iris 502

Samsung Galaxy Note 8 (Qualcomm Snapdragon 835)

The lens is made by a reputable photographic equipment manufacturer, as opposed to a low-cost unbranded lens.
